The SG? and your 3648's are 36 amps?
> Propane seems to give trouble starting in very cold temperatures.Well, no, it will start, but as the vapor is drawn off, the propane tank can cool down to the point it gets too cold to vaporize any more gas. The propane and generator companies have charts for how much HP and what size tank is needed for winter temps.
Don't muck around too much trying to get a conversion working properly, Conversions don't have the cold start enrichment (choke) that factory carbs have. converted rigs are a compromise. A dedicated propane engine has a proper propane carb.
As noted previously, we use a Stacked pair of the older SW+ 5548 inverters -- these are 11 years old (that is, these are NOT the new Conext SW line).
When Stacked, the inverters communicate via the Series Stacking Cable ... BUT it appears that the ONLY thing communicated, is Synchronization of the AC waveform.
It appears that the Series Stacked inverters (stacked to yield 240 VAC) are completely independent, as to Qualification parameters, Mac AC input currents, Charger voltage & time settings, and, unfortunately, there is also NO sync of when and how much current each charger takes from the genset, when a voltage-regulating charge stage is reached. This lack of input current sync can upset Inverter gensets, as the load on the gensset is often ALL on only one leg of the 240 V genset output.
Even when Series Stacked, the system is quite happy running on a 120 VAC genset (connected to only one SW inverter). Using just one inverter/charger in this 120 V genset configuration does NOT create a "Stacking Error" in the system.
Believe that muirhouse is also using Series Stacking on this SW/SW+ set of inverters.
Just trying to be clear about the almost complete independence of each inverter/charger, at least when Series-Stacked.
FWIW, based on experiences here with SW+es. Vic
Generally, portable gensets will have several outlets on the control panel. If one looks closely, there are almost always a number for the outlet molded into the front body of the outlet ... L14 - XX and similar.
These larger outlets would usually be a Twist-Lock (r) type outlet. You would normally look for the Mate to that receptacle -- so the receptacle would have an ' R ' at the end of its part number, and would want to find that same numbered plug, but with a ' P ' at its end.
Here is a link to some examples of some Plugs:
The circuit breaker on the gensset that protects that outlet would normally tell you a lot about that receptacle's current rating.
Good Luck, Vic
Backfeeding into inverters is not the question. Anyone done this? I
have done it once with a little Honda, but the plug was a borrowed one
(so was the generator) and I am not sure what we used.
If the AC inverter has an AC INPUT connection (120/240/whatever)--Assuming you make the appropriate voltage connection (i.e., 120 VAC, 120/240 split phase+neutral, etc.) and the right size circuit breaker and wiring--You should be OK.
If, you are planning on connecting to the AC output of an Off Grid Inverter (or even hybrid inverter)--Usually that is a fast path to letting the magic smoke out of much of your equipment.
Exactly, what AC inverter are you using right now?
So, I have the male, that goes into the generator, problem is, it is female on the other end, and needs to be a male. Then we have male to male
